| pi | Formula for pi/4 created by Leibniz. |
{% hint style="info" %} Curiously, despite being named Leibniz's formula for pi, this formula was not actually created by Leibniz. Bernoulli who was Leibniz's teacher and mentor discovered it; the book was then worked on and published by both of them. Leibniz had a curious arrangement with his teacher in which he bought all mathematical discoveries made by his teacher. {% endhint %}
